HUNTSVILLE, Alabama - A would-be robber walked unarmed into a Huntsville convenience store shortly after noon Saturday and demanded money from the clerk. He ran out empty-handed moments later after the clerk produced a big stick from behind the counter and hit him at least once in the head.

Huntsville police the attempted robbery happened at the Fast Stop at the corner of Meridian Street and Winchester Road. That is in north Huntsville just east of North Memorial Parkway.

A Huntsville police robbery investigator said the suspect is a white man in his late 40s or early 50s, between 5'6" and 5'8" tall, wearing glasses with a tattoo on his right arm. He might also have lacerations on his head, police said. The man fled in a PT Cruiser.

Police say the store had a video surveillance system, and footage will be released Monday if the suspect isn't identified and apprehended by then.
